Sell Your Galaxy A51
2019 · SM-A515F, SM-A515FDSN, SM-A515U, SM-A515U1, SM-A515W, SM-A515X, SM-S515DL
We pay up to £38, paid the same day.
A Galaxy A51 with a cracked screen, a worn battery or both is bought, but at a lower figure than the same phone in fully working order. Storage size - 64GB, 128GB or 256GB - also plays a part, so choose the capacity you actually have. The figure shown is what gets paid, not an opening position, and it is held for 14 days after our inspection confirms it.

Once we send your offer it will not drop, so you have time to decide.
We repair, so faulty still pays
Cracked screen or worn battery is a job on our bench, not a write-off.
Not the Galaxy A51 storage or condition you were looking for?
We buy a lot more than we list here. Older iPhones, Samsung and Pixel handsets, iPads, Apple Watches, MacBooks and games consoles all get a real offer, and a cracked or faulty device is still worth something to us because we repair them in house. Tell us what you have and we will come back with a firm price.
No obligation, and nothing to pay. We will not give you a number we cannot honour, so if we need to see it first we will say so.
Three steps
How selling your Galaxy A51 works
No haggling, no waiting on a callback, and no offer that quietly drops when you arrive.
Get your price
Pick your Galaxy A51 storage and condition above and the price we pay appears straight away, no waiting for a callback.
Get it to us, three ways
Walk into the shop, book a free collection from your door within 5 miles, or post it free from anywhere in mainland UK.
Paid the same day
Accept the offer and you are paid there and then, by bank transfer, or store credit towards an upgrade or downgrade.
Your price
What your Galaxy A51 is worth depends on
Storage
Bigger storage means a better price. Tell the finder above which Galaxy A51 you have and it prices that exact variant.
We take the Galaxy A51 in 64GB, 128GB and 256GB storage sizes. Pick the capacity your phone has when you request a quote, because the storage tier alters the figure and an accurate pick means the payment we confirm matches what you expected.
Screen condition
A cracked screen does not drop you to a faulty price. You keep the condition the phone is otherwise in and we simply take off what the glass costs us to replace, because we replace them ourselves.
Body and connector
Dents, scuffs and cracks to the casing are graded as part of the overall condition. A cracked back or a bent frame lowers the offer but rarely rules a device out.
The quote shown for your Galaxy A51 is not an opening bid. Once we inspect the phone and confirm the condition matches the one you selected, the figure stands and is held for 14 days, so you are not forced into an instant decision.
If you decide your Galaxy A51 should be repaired rather than sold, mendmyi runs a repair service as well as a buyback service. You are free to choose either route, and the repair side will not be used to talk you into a lower sale offer.
Battery health
We check battery condition ourselves on the bench rather than asking you to self-report a figure online, since there is no single on-device reading we can rely on for every brand. A genuinely worn cell comes off at what a real replacement costs us, worked out once we have the Galaxy A51 in front of us.
Condition is what moves the figure on a Galaxy A51: a cracked screen, a worn battery or both place the phone in a lower bracket than a fully working example. The phone is still bought, but you need to select the state that matches it when you ask for a quote.
The Galaxy A51's battery condition matters to us in the same way the screen does. If the battery no longer lasts as it should, declare that when you choose the condition - the offer then already accounts for it, and there is no reason to hide wear.
Whether it powers on
A device that boots and passes our checks is worth more than one that does not, but a dead handset is still worth telling us about rather than binning.
iCloud or Google account lock
We can only buy your Galaxy A51 once it is signed out of your Google account, which is what clears Factory Reset Protection.
Before the Galaxy A51 leaves you, sign out of your Google account and remove the screen lock, PIN, password or biometrics. This clears Factory Reset Protection, the security layer that otherwise keeps the phone linked to your personal details.
Original parts matter to the price: an aftermarket screen, battery or camera fitted by someone else changes what we can pay. If you are not sure what is in your Galaxy A51, our guide on how to check a refurbished phone walks through what to look for.
Five minutes
Before you sell: five minutes that protect you
Do these before you hand the device over and the sale goes through without a hitch.
-
1.Back up what you want to keep
Photos, contacts and anything else you would not want to lose. If an upgrade is replacing it, here is our guide to moving everything to your new phone.
-
2.Sign out of iCloud or your Google account
Turn off Find My before you hand over the Galaxy A51. A device still signed in cannot be bought from you.
-
3.Take out the SIM and any memory card
These are yours to keep and are not part of the sale.
-
4.Note down the IMEI
Dial *#06# or check Settings to find it, in case you want a record for your own files.

No surprises
Ownership, ID and your data
Three things worth knowing before you sell anything to anyone, not just to us.
The device has to be yours to sell
We cannot buy a device that is still under contract or on finance, because until it is paid off you are not yet its legal owner. We also cannot buy a device that is part of an ongoing insurance claim, or that has been reported lost or stolen.
"This device is not under contract or finance, is not part of an insurance claim, and has not been reported lost or stolen - I own it outright."
We record name, address and ID on every purchase
We record the name and address of everyone we buy from, and check them against photo ID and proof of address. HMRC requires it: buying from a private seller, we have to raise the purchase invoice ourselves and it must carry your details. Bring the documents into the shop and show us, or send a photo if the device is reaching us another way.
It protects you as much as us: the purchase can always be traced back to a genuine sale rather than an anonymous one. A photocard driving licence showing your current address covers both documents on its own.
GOV.UK: VAT margin schemes, section 6.2Your data is wiped at our shop
Once your device is checked in, it is fully wiped and factory reset at our shop before it goes anywhere else. Nothing of yours is left behind on it.
Locked in
Your price is held for 14 days
Once we send you an offer for your Galaxy A51, it is held for 14 days. That gives you time to compare us against the online recyclers before deciding, without the price moving under you.

Selling your Galaxy A51
What identity checks do you run when I sell my Galaxy A51, and when is payment sent?
Every Galaxy A51 sale is checked against photo ID and proof of address, with no exceptions. Once those checks are confirmed, payment is sent the same day, whichever way the device reached us.
Should I repair my Galaxy A51 instead of selling it to mendmyi?
There is no automatically right answer, because mendmyi repairs Galaxy A51 handsets as well as buying them, so you can choose either route on its own merits. We are not steering you towards a repair or a sale - both services are open to you.
How long does a confirmed quote for my Galaxy A51 stay valid?
Once we inspect your Galaxy A51 and confirm the offer, the figure is held for 14 days. That gives you time to decide without feeling rushed once the price has been agreed.
Will mendmyi try to reduce the amount quoted for my Galaxy A51 after the phone arrives?
No, the quote is not negotiated down when the phone arrives. The figure shown for your Galaxy A51 is what we pay, not an opening position; once the phone matches the condition you selected, the amount stands.
If the screen on my Galaxy A51 is cracked and the battery has seen better days, do you still want it?
Yes, we still want a Galaxy A51 with a cracked screen and a worn battery, and you can select that combined condition when you ask for a quote. The figure you see then already reflects both issues, so our inspection will not change it.
What do I need to clear from my Galaxy A51 before selling it to you?
You need to sign out of your Google account and remove the screen lock, PIN, password or biometrics before we buy the phone. Clearing these turns off Factory Reset Protection, so the Galaxy A51 is no longer linked to your details and can be processed without a hold-up.
